Customer recently got adsl, but email (outlook) will not work.

I first check that everything is setup correctly.

Then, I reconfigure outlook from the original dialup account details to the new adsl details.

At this point, the test button is successful, but sending fails without any error messages.

This is starting to sound familiar… I had a similar outlook problem not long ago, except:
I setup outlook express & it works flawlessly.

As I explain this to the customer, he says he doesn’t mind using OE, especially considering that the other option would be to re-install outlook.
